Overview
The Simrad SS175L is a 1 kW low CHIRP thru-hull transducer with a stainless steel housing and a built-in tilted element to correct for hull deadrise. It runs in the 40 to 60 kHz band with a 32° to 21° beamwidth, and it supports depth plus fast-response water temperature sensing.
Connection is via a black 9-pin connector on a 10 m (33 ft) cable, which helps when the run to the helm or sonar module is not short. The physical envelope is about 134 mm in diameter by 118 mm in height, and installed weight is 2.7 kg (6 lb).
This style of low-frequency CHIRP transducer is a practical fit for offshore runs, deeper channels, and boats that want bottom tracking with broad coverage, especially when you are not staying in shallow water all day.
Key features
- Low CHIRP operation in the 40 to 60 kHz band with a 32° to 21° beamwidth
- 1 kW power rating for compatible sounders and sonar modules
- Depth and fast-response water temperature sensing in one thru-hull
- Tilted element options (0°, 12°, 20°) to correct for hull deadrise at the mounting point
- Stainless steel thru-hull housing with a low-profile outside footprint
- Black 9-pin connector with a 10 m (33 ft) cable
- Approx. 134 mm diameter x 118 mm height; 2.7 kg (6 lb)
Variants
The SS175L is offered with different internal tilt angles. Across the range, the key difference is the tilt of the element inside the housing, which affects how straight down the beam points once the transducer is installed on a hull with deadrise.
Tilt selection is based on the deadrise angle where the transducer will actually sit on the boat. The connector style and cable length remain the same across these options.
- 000-13774-001: 0° tilted element (for 0° to 7° deadrise). This suits flatter sections near the keel where the mounting surface is close to level.
- 000-13775-001: 12° tilted element (for 8° to 15° deadrise). This matches moderate V sections where a flat transducer would aim the beam off to one side.
- 000-13776-001: 20° tilted element (for 16° to 24° deadrise). This supports deeper V running surfaces so the beam stays closer to vertical at the mounting point.
Compatibility and fit
This is a single-band, CHIRP-ready transducer intended for low-frequency operation. Confirm your Simrad sounder or sonar module supports a 1 kW low CHIRP transducer and a black 9-pin transducer connection, or the correct adapter cable for your port type.
Measure deadrise at the intended install location rather than relying only on published hull specs. A small shift fore or aft can change the angle enough to move you into a different tilt option.
Installation and setup
Installation is a thru-hull cutout with the transducer sitting close to the outside of the hull. Typical hole sizes are 95 mm (3-3/4 in) for fiberglass or wood hulls and 105 mm (4-1/8 in) for metal hulls.
Plan the placement for clean water flow and a reasonable cable route to the helm or sonar module, then bed and torque the hardware per the supplied instructions. On metal hulls, follow standard yard practices for isolation and bonding to manage galvanic concerns.
Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.
Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.
Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.
Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.
Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.
Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.
To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
